Magnetic resonance imaging is now the diagnostic imaging procedure of choice for patient follow-up after acoustic neuroma surgery. Magnetic resonance imaging provides an excellent view of the cerebral pontine angle.

Implantation of palpebral springs in patients who suffer from paralytic lagophthalmos are commonly used to correct exposure keratitis and improve eyelid closure. Eyelid springs are fashioned from orthodontic wire. Although orthodontic wire usually is not magnetic, some wires may contain ferromagnetic metal that could result in patient injury.

Report of a Case.  —A 26-year-old white female presented with a right seventh nerve palsy. In 1980, an acoustic neuroma was removed and an eyelid spring fashioned from orthodontic wire placed. The spring was tolerated for 8 years. In September 1988, a magnetic resonance imaging scan was performed for follow-up evaluation of the cerebral pontine angle. During the examination, the patient noted vibration of her eyelid spring. During
